x86: create space in bios memory map As of now, we mark the top 1MB of memory space as unusable. Part of it is actually usable and is required to be marked so by some of the newer versions of linux kernel. This patch marks the top 639KB as usable. This value was chosen by looking at QEMU's output for bios memory map.
